There is no way the restaurant/bar industry would tolerate a 20% loss of CO2 within the distribution system. If that were a reality, then bar and restaurant systems would be hard plumbed to guarantee NO loss.

I call BS on the claim as a general statement.

Does the restaurant/bar industry use the same tubing we do? Since david_42 pointed out the diameter I'm thinking the "Normal airline tubing" is cheap aquarium tubing. I'd also imagine the 20% is the inline volume per day/week/year.

I call TOTAL BS. This has "marketing ploy" written all over it, (with bad grammar to boot!)

Normal airline tubing can lose up to 20% of CO2 through its membrane. Silicone tubing reacts w/ CO2 and render it less efficient (thus the silicone hardening over time under CO2 usage). Our special CO2 Resistant Tubing loses less than 1% of CO2.

What does that even MEAN? "Can lose up to 20% of CO2"? 20% of what? Of the gas passing through it? So for every liter of gas I pump through the line, 0.2 liters escapes? I think I'd notice that. 20% of the gas in the tank? 5 lbs CO2 has a volume of 305 gallons at STP...so does this mean that as soon as I connect the hose to my tank, I lose 0.2*305 or 61 gallons of CO2? I think I'd notice that too. No timescale is listed here....and since the rate of diffusion through the line would not depend on the size of the tank, what are they claiming the leakage is 20% of?

I would not buy into this crap. Buy your hosing at menards for 25 cents a foot and call it a day.

Ok, coming from the offroad world. I can tell you for sure that co2 will leak out. It can leak out of smaller spaces than air can. Tire walls even. If you fill a tire with co2 (common practice in offroading) in a month the tire will be back down to the preasure you started at (5 psi or similar). This is the rusult of it leaking out of the tire walls. I have filled my tires with co2 to drive my rig home, but then drained them and refilled them with air from my compressor to keep my preasure.
